This sets the threshold (0 to 600) that triggers a fault for far-end frame loss during a frame-loss measurement test, mirroring the near-end threshold but for loss occurring on the remote MEP's side of the association rather than the local ingress side. An admin sets this independently from the near-end threshold because near- and far-end loss can have very different causes and tolerances, and a service could be failing on one side while the other stays clean. For example, a far-end threshold breach while the near-end stays fine would direct the admin's troubleshooting toward the remote site or the path segment closer to it, rather than anything local.
